VBE = 10V in LTspice sim?

Hi,
Why is VBE of Q1 equal to 10V in this attached (albeit non realistic) LTspice sim?

No attachment.

I get 0.65V. Depends on temperature and current and what type of transistor.

If you are getting 10V Vbe, then you are likely putting many amps through the base-emitter junction (which would blow the transistor in real life).

I wish spice had "smoke".
SPICE has a 1,000,000A voltage source that can drive a smokeless diode to 10 volts.
